How to setup a zero point calibration ?
It is necessary to establish the true zero flow condition and program that set point into the instrument. If the zero set point is not at true zero flow, a measurement difference may occur. Because every flow meter installation is slightly different and sound waves can travel in slightly differen...Read more -
How to judge the liquid flow direction for our flow meter ?
Make sure that the instrument works properly Check the flow rate for the indication. If the displayed value is positive, the direction of the flow will be from the UP transducer to the Down transducer; if the displayed value is negative, the direction will be from the Down transducer to the UP tr...Read more -
Temperature sensor installation
(a) 6.2.1 CLAMP-ON TEMPERATURE SENSOR When determining the installation position of temperature sensor, we should pay attention to the pipeline surface. Pipeline surface must be clean before installing temperature sensor, then use belts to fix temperature sensor. (b) 6.2.2 INSERTION TEMPERATURE S...Read more -

Portable flow meter transducer cables
After the transducers A and B inserting into the pipe, the sensor cables should be routed to the transmitter location. Verify that the supplied cable length is sufficient to meet the installation requirements. While transducer cable extension is not generally recommended, if additional transducer...Read more -
Couplant of portable flow meter
Assure an acoustically conductive path between the transducer face and the prepared piping surface, a coupling compound is employed. Enclosed with the Doppler flow meter system is tube of Dow Corning 111, silicone grease. This couplant is satisfactory for temporarily mounting the transducers to t...Read more -
The installation of clamp on flow sensors transducers of portable Doppler flow meter
1. Place each transducer under the strap with the flat face positioned towards the pipe. The notch on the back of the transducer will provide a mounting surface for the strap. The transducer cables must be facing in the same direction for proper operation. NOTE: Large pipes may require two people...Read more -
